Dual Sim

I've a question
Is it possible to use 2 sim's in the 2020 and use 1 for permanent gprs access and the other for my regular phone conversations without swapping the sims in any program all the time.
This because my vodafone charches me for every minute i use gprs and T-mobile offers a 10euro package for unlimited gprs time. so if its possible i'll aply for a Tmobile gprs package.

Nobody ?

No.
AFAIK you can only access one sim at a time, with either physical dual sim adaptors or multi-sim copiers.

Missed calls when I have an active UMTS connection

Hi everybody
I have recently started to use "push" email on my XDA Exec and so my data connection is active all the time. I have found that when I am in a 3G coverage area, I occasionally miss incoming voice calls (about one in five got missed in my testing today). The caller gets diverted immediately to the voicemail system. This does not occur if I don't have a data connection active, or if my data connection is a GPRS one.
I have contacted T-Mobile to ask about this and they tell me that it is not possible to receive a call when there is 3G data being transferred. I am not sure about this since I thought that one of the advantages of 3G over GPRS was that it allowed a data connection and voice connection simultaneously. Indeed even a GPRS connection gives priority to an incoming voice call so that the call can be received and the data connection gets suspended for the duration.
Does anyone know how to make the 3G data connection not prevent incoming voice calls.
My phone is an O2 XDA Exec with radio version 1.09 and with a T-Mobile Web'n'Walk SIM.
Thanks in advance for any help.

I'm sorry I don't know the answer, but I can tell you I have the exact same issue (O2 Exec with T-Mobile Web 'n' Walk SIM). I got fed up with missing practically every call. ..instead I get voicemail a few minutes later. I'm stopped using push e-mail with a hosted Exchange account and I've reverted to checking via POP every 15 minutes or so, to see if that helps.

Thanks for the confirmation that it isn't just me, Izzard-UK.
I have done a bit more testing and discovered a few more things. It seems that I always receive the call if my phone hasn't received a call for a while, but once I have received a call, I can't receive a call for several minutes afterwards(I don't know how long but it is in the tens of minutes). And just to confirm, this is only if I have a UMTS data connection at the same time. Without the simultaneous data connection, all is well
Izzard-uk, can you confirm whether this "first call works - subsequent calls don't" behaviour is the same for you as well.
For me, the temporary fix is to send my phone to "GSM" instead of "auto" so that it uses a GPRS data connection instead of UMTS. Of course, data transfers are much slower but I can live with that!
I am going to try upgrading my radio ROM tonight (to 1.13) to see if that makes any difference.

I have tried upgrading to radio version 1.13 but it made no difference.
Does anyone have any other suggestions?
Thanks for your help.

Hi Guys,
I use TMC option of TomTom on my Universal with data connection always on (essentialy UMTS 3G) and email checking every 30min and I can receive calls without any limitation... I did it with 1.09 radio rom and actually 1.13 radio rom.
Everything is ok for me. But I noticed that on UMTS (not happening on GPRS only), signal indicator is set to 0 when I wake up the universal and get real signal strenght after few seconds. But I can receive call any time...

When i was with orange and had a 3g signal i could surf and talk, i also though this was the normal with 3g....
How ever on t- mobile it seems not my phone is set to check email every so often so im always getting missed calls where they dont get through when the mda is checking emails so ive had to lock it to 2g annoyingly enough

I have an O2 contract as well as T-Mobile and if I do a test with my O2 SIM in my Exec I don't see the missed calls problem at all. It seems to be only on T-Mobile that I have this problem.
Unfortunately, as I said in my original post, T-Mobile say that it isn't a problem because simultaneous voice and 3G data isn't supposed to be possible!
Argh!!!!
I suppose I will have to put up with it since their Web'N'Walk deal has no competition at the moment in the UK.
Mark

whos says its not actually possible out of interest?

I raised this as an issue with T-Mobile Customer Services. They asked me to make a list of when missed calls happened so that they could trace the calls and determine the reason. I did this and sent them the details - out of a total of 19 test calls over a 24 hour period, 5 had gone straight to voicemail even though I had a perfectly good signal at the time.
But the annoying thing is that, after going to all this trouble, they just sent me an email by return saying that it was not possible. I have quoted the email below.
Hi Mr Burgin,
I have just received feedback from our engineers who have tested out the problem you have described. The has advised me it is not possible to receive a call whilst transferring 3g data. I hope this sheds some light on the problem you were receiving.
Regards....
Not a very satifactory answer, in my opinion.
Mark

Hmm, no that's rubbish! Clearly other operators can manage it. You just know this is a checkbox in some management software somewhere:
"Allow telephony during UTMS transfer? Yes/No"
I've gone back to my HTC Wizard. Yeah, smaller screen and no 3G. ..but it feels a lot snapier than the Universal I've been using. And I can receive calls now, too!

Mark, I've had a thought. Do you (like me) have an old 5v T-Mobile SIM.
These SIM’s can be identified either by SIM serial number 893044 05 or 16 – up to and including 893044 50. SIMs with serial numbers 893044 52 and above will be ok- anything lower is likely to be a 5v.
There was an issue when I 1st got my MDA Pro. It had to be network unlocked by T-Mobile for it to work with my SIM. Is it possible that the ROM update as "re-awakend" this problem?

Orange SPV M600 - GSM Dial Up Modem settings?

Hi Guys,
OK, here's the situation. I have an Orange SPV M600. I have an Orange SIM card inserted that has *NO* GPRS functionality (it's my corporate SIM card and they've locked down GPRS for everyone).
What I'm trying to do is dial up to the internet using dial up WAP. What would be the settings for these? All I want to do is be able to maybe send and receive POP emails on the device and maybe slowly browse the internet occasionally.
Any ideas? What would the setup setting be? ANy contributions gratefully accepted

You mean you want to dialup using plain old CSD? That would be easy if that's the case - just setup a new connection and punch in the number of the modem pool of your ISP, and that's it. You got 9.6 baud, unless you have HSCSD - but given that your company locked down GPRS....

normaly WAP also use the same "modem" as gprs
and the diff betwene real grps internet and wap is
handled at the server side depending on the AP

Changed my mind...dual SIM is now the solution!
Thanks Guys
I came up with a different solution though. A Dual SIM adapter. One for my workplace SIM and I'll buy another PAYG SIM with the cheapest data charges and switch between them when I want to make data calls etc. Seems like an ideal solution However, that opens another can of worms....
Which Dual SIM adapter do I get? It has to fit the SPV M600 (HTC Prophet) and I like the idea of being able to switch SIMs whilst the unit is online but I understand these ones really drain the battery. The other one, I understand, does not require power but to switch SIMs, you have to power the phone (or is it unit?) off and on again. Hardly an elegant solution!

kind of a dual sim question

I have a new job, and with that comes a new phone (KPN), but: no data traffic! (company policy)
I do own a private number (Tmob) which I can update to a data-plan. And to make use of them, I could use a sim-switch, but then I have to switch each time I want to use internet or make a call. But I don't wanna switch! I want 1 sim for voice and 1 for data at the same time, is this impossible??!
probably
But then: as an alternative I could ask KPN for an data only contract as an addon to the contract of my work sim which will be billed by myself. Does anyone have some experience with this? (calling KPN is not possible during the weekend, and I'm very curios)
thanks!

dual sim
Hello,
I tried a dual sim solution in my trinity, but without success. I bought the latest generation because the older ones can't deal with digital sim's capable of umts. This was a 16th generation dual sim. It worked fine in a verry old nokia but not in my trinity. Tried it in WM5 and WM6 but keeps reporting a sim error.

Receiving MMS on SIM not set to LTE

I'm seriously thinking about picking up this phone (I asked a question related to Android for Work a few days ago), but want to make sure I know what I'm getting. I have a question regarding receiving MMS on whichever SIM is not set to default for LTE. I believe I understand how data works regarding the dual sim setup on the phone -- both sims have the ability to connect to LTE, but only one sim can connect at time. The non-LTE set sim will only connect to 2g/3g for voice/text (no data even if connected to 3G, correct?).
My question is very specific: If I have LTE set to, say, sim 1, what happens if someone sends a MMS based group message to me on sim 2? I figure one of 3 things happens:
1. The MMS is downloaded and received automatically (whether through 2G/3G on SIM 2, or that somehow SIM 2 switches to LTE in the background so that it can download the MMS)
2. The MMS is not downloaded, but SIM 2 receives a sms notification that an MMS is ready for download (which would be done by either just tapping download to make the phone switch LTE to SIM 2 in the background, or by manually switching the LTE to SIM 2, then tapping download)
3. There is no indication on the phone that an MMS has been sent to SIM 2, and I either miss it completely, or only see it if I just happen to switch LTE to SIM 2 at some later date (before the expiration date, anyway).
Can anyone help to clarify this for me? I can live with options 1 or 2, but 3 would be difficult to live with. SIM 2 would be for work, and MMS-based group messages are sent out when urgent issues come up (work in IT, and I am on call often).
Thanks!

I got an answer elsewhere so I figured I put it here:
"I wish there was a better way they could've done this. When you get a mms on the "non data" SIM- it will give you a notification if you want to download it. When you eventually agree- it temporarily changes to that SIM's data to fetch.
Both SIMs have LTE so that's not a problem. Group texts are kind of a nightmare when it comes to the non data SIM."
